Some help on doing the spice assignment... The easiest way (recommended): -Go to the Kelley lab and log into one the Linux machines there. -Using the text editor from the menu pulldowns, create your spice file. -Assuming that you named your spice file "bob.sp"... run Hspice by typing: hspice bob.sp >! output_bob -Note that I used " >! " not ">|". I was making an assumption that you were using a different command interpreter (Bash) instead of the one COE gives you which is C shell. You can find out your command interpreter by typing "echo $SHELL" (case sensitive) For more learning: -Log into a COE Linux machine with ssh. -Using a programming editor such as "vi" or "emacs" edit your spice file. You will find many tutorials on the web that can help you learn them. I recommend "vi". Either is fine. -Run spice as above. For the hard core: -Go find the latest source code for ngspice on SourceForge. -Compile source code on your machine -Do the assignment. To play with a gui-spice -Download LTspice (LTspice works on Linux or Mac OS X under "wine" (a windows api shell) -Note for Mac or Linux users: ssh is already available to you in your shell (terminal in Mac) Also,... you have X11 support available (free, as in beer) so that other gui-based COE tools that are able for you to run on your laptop.
